kwok is slow enabling deployments

[himred]

How to use it?

• kwok
• kwokctl --runtime=docker (default runtime)
• kwokctl --runtime=binary
• kwokctl --runtime=nerdctl
• kwokctl --runtime=kind

What happened?

I'm using kwok with docker (kwok version v0.6.0 go1.22.3)
When I create 600 deployments (1 replicas, 1 namespace, 1 service for each deployment)
The 600 pods are created instantly
The 600 services are created instantly
The 600 deployments are created instantly BUT they are not ready: ie
ns99 fake-deploy-492 0/1 1 1 1m31s

On average on my beefy server it takes around 2 mins for them to be all ready, monitoring further shown that on average kwok validate 5 deployments/second.

I did the same with 50K deployments, it took almost 3 hours.
Any option to speed up this as there is no reason to take 0.2s to enable a deployment.

Any help, advices appreciated.

Thanks !

What did you expect to happen?

I expected to be fast.

How can we reproduce it (as minimally and precisely as possible)?

Yes, just deploy 600 simple deployments

The bottleneck for this is the kube-scheduler; you need to increase its qps limit.
